population control:peer review sources

"Human influence on the planet has increased more human population"
Our population has increased a lot and because of that we have more problems becasue we are contributing more than we put out. Acording to this article by JSTOR from 1860-1991 human use of energy went from 1 billion megawatt hours per year to 93 billion megawatts hours per year and that is probably way over the limit now.
".....In 1992 assumed that the Worldwide average number of children born to a women during her lifetime at current birthrates would fall to 2.5 children per women...by 2050 the number would in increase to 12.5 billion.

This is very interesting how population goes. Its a bad thing that we are becoming over-populated, but at the same time we dont want to limt so much that we become under-populated so how do we fix the problem with creating a even bigger problem?


Another reading that I read was a short passage of a critique of someones writing on population control. One quote that stuck out to me was "population in different trophic levels are expected to differ in the methods of control." It stuck out to me because I don't quite understand what it means and i that's something I can further study on. Other things that came up in the reading was carnivore and herbivore and how than stand with the whole population control.

Nate Lewis

Nate Lewis discussion on energy and climate change started get interesting towards the end once he started to name the energy sources and which ones were best to be used. The whole was a little confusing though when he mentioned terawatts and how energy is converted by a certain number of terawatts I was like whoa what does all this mean and I am still confused on that but after reviewing my notes i understand it but more.
Something that was interesting was when he mentioned that renewable energy is good all idea in all but we would still need some technology to create. We have trying to promote renewable energy and not even thinking about how money and human energy it would take just to create the energy needed to power everything.

population growth and climate change

Something that is interesting to me is population growth and how it is affecting our planet. I think it is interesting that we are getting to the point where the earth is over populated and i would like to do more research on it. I don't know exactly what topic in population growth I would like to do but I know its something I'm interested in studying more of. I read a few articles and saw a few growth maps, what interested me the most is a map of the world 2000 years ago. There were only 300 million people on earth and by 1995 it when up to approximately 6 billion Asia holding 61 percent in population. Of course this number has went up and is now affecting our food,water, and shelter.

"Math in Daily Life -- Population Growth." Teacher Professional Development and Teacher Resources by Annenberg Media. Web. 12 Feb. 2010. http://www.learner.org/interactives/dailymath/population.html.

"By 1990, that rate was down to 1.5%, and by the year 2015, it's expected to drop to 1%. Family planning initiatives, an aging population, and the effects of diseases such as AIDS are some of the factors behind this rate decrease." This quote was interseting it says that instead of population increasing as we thought it would it will decrease by the year 2015 due to health and aging. I was glad I was able to find this quote because now I am able to compare and contrast my information. I somewhat believe this data and it does make sense but I also heard that for every person that dies a person is born so regardless if someone dies we would just be replacing them with someone else. So maybe this is not an accurate asumption.

This website showed a lot of different graphs and maps of populatation growth and why it is continuing to grow. A part that struck me was fertilty growth. "the current growth of population is driven by fertility." They showed a map of the world what this map shows is the total fertility growth around the world during 1990
